OK.  So mostly revert to Emacs-23 behavior.

We may as well get rid of pop-to-buffer-same-window (those who want to
provide a LABEL can use pop-to-buffer instead).

Note that (set-window-buffer (selected-window) buffer) isn't quite good
enough, since set-window-buffer will be happy to change the buffer of
a mini-window, whereas callers of switch-to-buffer that want to operate
on the selected window should signal an error in that case.
I think adding a `selected-window-only' argument to switch-to-buffer is
a better solution so callers don't need to worry about such details of
